Thanks for the lead. Requesting any sound that is not defined gives the
Default Beep. The solution is ...

using System.Runtime.InteropServices ;

[DllImport("winmm.dll")]
public static extern long PlaySound( string lpszName, long hModule, long
dwFlags );

PlaySound( " ", 0, 0 );

Is it safe to assume that every Windows machines has winmm.dll installed or
should the PlaySound call be protected with a Try/Catch?
